Robin Williams’ kids Zak, Cody, and Zelda, were at the World Series game at AT&T Park on Sunday. The Williams’ kids all wore custom San Francisco Giants jerseys with their dad’s name on the back. According to Us Weekly, they were joined by one of Williams’ best friends, Billy Crystal, for an emotional tribute before the game. Zak, 31, threw out the first pitch.

“Images of Williams’ best-loved films were mixed with videos of his various visits to San Francisco Giants games as part of a touching video montage which shone down on his favorite ballpark from the main center-field scoreboard.”

Robin Williams loved his children — and loved baseball. Most people did not expect to see his children come on to the field with smiles on their faces, but it’s something that their dad would have loved. The crowd cheered loudly for Zak, Cody, and Zelda, and there were many tears shared between Giants fans and Royals fans alike.

“We are honored to be here in support of the tribute to our father, someone who loved his hometown and especially the Giants. For all of us, it is a tremendous delight and a little surreal to throw out the ceremonial first pitch of a World Series game for our team to our dad’s best friend. We could not think of a better way to celebrate his memory. Let’s go Giants!”

Robin Williams’ daughter Zelda has been quite vocal since her dad’s passing. Although she ran into a few Twitter trolls over the past few months, she has really been a light during the darkest times. As previously reported by the Inquisitr, Zelda recently got a tattoo in memory of her dad.

Hollywood tattoo artist Dr. Woo drew Zelda a hummingbird along with her father’s birth date on her wrist. The location, though somewhat popular for ink, has a very special sentiment for Zelda.

“I’ll always put my hand out to shake with a smile,” Zelda wrote in a caption with a photo of the tattoo on Instagram. Her father loved meeting new people and always wanted to make them laugh. This made him happy, and it sounds like it makes Zelda happy too.
